This sudden transition is accompanied by the growth of a surface structure responsible for deactivation of the process. Analysing a simple phenomenological model of a generic surface process shows that the growth of this deactivating structure implies a hysteresis according a forward and reverse scan in the external control parameter. Application to water electrolysis, metal passivation and ethylene oxidation on Rh/TiO2/YSZ under open-circuit and under electrochemical promotion is discussed.[SACE]Process desactivationElectrochemical dischargesNEMCAWüthrich, RolfBaranova, Elena240027Bleuler, Hannes104561240416Comninellis, Christos10480761199-1205Electrochemistry communications252005GGECU10173252016LSROoai:infoscience.tind.io:85921STIarticleLSRO-ARTICLE-2006-010EPFLREVIEWEDPUBLISHEDARTICLE
